FOLDING GATE..

l To all whom zzf may concern lther following is a specification.`

Be it known that I, KARL ToBiAs, ajsubject of thel Austrian Emperor, King of 'Hungary, and resident of Budapest, in tlieEmpire of Austria-Hungary, have invented a new and Improved Folding Gate, of which This invention relates to a folding gate which is intended especially for the platforms of railway vehicles and which consists of a plurality of movably connected bars which when the gate is expanded extend partly horizontally and partly vertical. The length of at least two of tliehorizontal bars corresponds to the width of the plat` form opening, and allthe horizontal bars are hinged atone end to one ofthe sides of said opening and may be swung down in their own plane around the respective hinges. Gpposite to the latter, fastening devices for the other ends of the bars in question are provided at the other side of the` platform opening. The configuration of the horizontal bars is such that when they have been swung downward, z'. e. into vertical po-y sition, they lie partly one over the other and partly side by side, irrespective of whether there are but two or more of, such bars.

. The vertical bars, however, which are alternately connected to one and the other side of the horizontal bars remain always vertical, but form two sets or groups, one being lo-l cated upon the outer side, the other upon the inner side of the other bars. Therefore, all bars together, when the gate is collapsed, require but very little space. ln fact, it is l practically merely double the breadth of two of the vertical bars. This minimum space required for the collapsed gate is, however, not the only advantage of the new construction in question. 'Further advantages reside second in the very convenient collapsibleness or foldableness of the gate, third, in the safety of the gate when in its locking position, and fourth, in the gate being practically not subjected at all to wear and tear. In order to make my invention more clear, I refer to the accompanying drawing, in which similar letters denote similar parts y throughout the several views, and in which:

is ythe lst ep leadingtothe platform. At the right side ofsaidopening are 'provided hingesl 8 arranged in, one vertical line,l or

plane and having attached to 'them thebars 3 which have 'a' lhorizontal position .when

bars 3 are crooked, as"shown, in such a manthe free or crooked end ,lofthe upper bar lof which they form parts, is ,ex-.f panded, as shown iny Fig.` 1'.; The bars 3l vmay ,be swung downward from the .positionv represented in Fig l to that -representedin Fig. 4 7 whenv the-.folding-gate will be' col-'f `lapsed and, the platform accessible. The

will lie exactly over the free or crooked-end of the lower bar, but side by sidewith the hinged. end orhalf of the same, as repre-` Y lsented in Fig.4 infull lines and in Fig. `1 in dotted ones. The vertical bars 6, 7 however, which arev movably connected with the crooked bars, by means of bolts or the like, and which `alternate with respect to the front side and the rear side of these bars, are separated some distance one from the other when the folding gateis expanded, and lie side by side when it is collapsed. Iny the form of construction shown, there are three horizontal bars 3, and four vertical bars 6, 7, 49, 10, the bars 6 and 9 being located at the outer side and the barsy 7 and 10 at the inner side of the bars 3. `The bent bar 5 atlixed to the uppermost bar 3 serves` as a handle. As matterof course, there may be more than four vertical bars and more than three horizontal ones, and where the lowermost of the horizontal bars is rather near to the platform, as in the formy secure in position, the y l next lower one. 16 forming between them a guide groove which is widest at its lower end where the bars enter the groove. One of the ridges forms an upwardly extending point- 13 and,

at the side of this point, an auxiliary groove let, the bottom of which serves as support proper when the end of the bar has passed through the narrowest part 12 of the main groove, as well as over said point. The end of the bar is represented in three different positions; first, when entering the main groove; then when passing just over the point 13; and finally when having arrived in the auxiliary groove 1%. It is obvious that the gate is now safely locked by its own weight. The part 13 being pointed or wedge-shaped, and also the lower side of the `bar end being sharpened, as shown (F ig. there is no possibility ofthe bar assuming any intermediate position, but it locks the gate either not at all, or completely. rIhe other horizontal bar is held in position by means of the part 17 (Fig. 6) which has a guide groove 12 similar to the main groove of Fig. 5. That guide groove is, however, closed at its upper end, there being merely left as 4much space as is required to lift the upper bar over the point 13, as described. The ridge part 18 (Fig. 6) serves as a stop, preventing the whole gate from being raised more than is necessary to effect the locking.

Having now described my invention, what The support has ridges I desire to secure by a patent of the United States is:

1. In a platform folding gate for railway vehicles, the combination, with a plurality of'horizontal, vertically crooked bars and a hinge for one end of each bar, of vertical bars movably connected with said first-mentioned bars and distributed upon the two sides of the same, and of a support for the free end of one of the same, said support having an upwardly extending guide groove and a downwardly closed supporting groove, substantially as shown and described.

2. In a platform folding gate for railway vehicles, the combination, with at least two horizontal vertically bent bars hinged each at one end and adapted to be placed one partly above the other and partly side by side, of a support for the free end of one of said bars and of a guide for the free end of the other of said bars; said support having an upwardly extending guide groove, a downwardly closed supporting groove, and a lug between the upper ends of said grooves, the upper end of said lug being wedge-shaped, substantially and for the purpose as described.

In testimony whereof I affix my signature in presence of two witnesses.
